en.Wedoany.com Reported - The Ascó I Nuclear Power Plant, located in Tarragona, was disconnected from the power grid in the early hours of May 9, officially commencing its 31st refueling outage.

The main scope of the outage includes replacing more than one-third of the fuel elements in the reactor core, involving a total of 60 fuel element replacements. At the same time, numerous inspection and preventive maintenance activities will be carried out, including replacing the coolant pump motor of Reactor Building (BRR) B', conducting a comprehensive overhaul of the seals for BRR 'C', cleaning the secondary side of the steam generators, performing laser profilometry inspection on the reactor pressure vessel head thermal sleeves, and conducting remote visual inspection of the exterior of the pressure vessel head. Furthermore, 21 physical design modifications and 7 computer software modifications will be implemented during the outage, as these facility improvements can only be completed during shutdown periods.

It has been disclosed that the total budget for this refueling outage project is 27.5 million euros. The previous refueling shutdown maintenance for Ascó I Nuclear Power Plant was originally scheduled for the fall of 2024. Notably, the Nuclear Safety Council will decide this summer whether to extend the plant's operating license until 2030.
